Grounding structure of electrical connectors

Abstract

This invention relates to a grounding structure for an electrical connector, comprising: an insulating body having a first mating space inside and a plurality of terminal slots on both sides of the first mating space, and receiving slots formed on the opposite outer sides of the plurality of terminal slots on both side walls at the bottom of the first mating space; two terminal groups passing through the plurality of terminal slots of the insulating body, each terminal group having a plurality of signal terminals and a plurality of ground terminals arranged in an alternating manner; and two grounding plates installed in two receiving slots of the insulating body, each grounding plate having a plurality of abutting spring arms that abut against the plurality of ground terminals. The plurality of abutting spring arms of the two grounding plates of the aforementioned insulating body abut against the plurality of ground terminals to form an electrical connection, thereby enabling the plurality of ground terminals and the two grounding plates to form a common ground and to isolate and eliminate electromagnetic waves and crosstalk.

Claims

1. A grounding structure for an electrical connector, comprising: An insulating body has a first mating space inside and a plurality of terminal slots on both sides of the first mating space. A receiving groove is formed on the two side walls at the bottom of the first mating space corresponding to the terminal slots on the opposite outer sides. Two terminal groups are inserted into the terminal slots of the insulating body. Each of the two terminal groups has a plurality of signal terminals and a plurality of ground terminals arranged in an alternating manner. Two grounding plates are installed in the two receiving grooves of the insulating body. The two grounding plates are provided with a plurality of abutting spring arms that abut against the ground terminals.

2. The grounding structure of the electrical connector as described in claim 1, wherein the insulating body further has a second mating space with a length shorter than the first mating space, and an isolation portion is provided between the first mating space and the second mating space.

3. The grounding structure of the electrical connector as described in claim 2, wherein the second mating space is provided with two additional rows of multiple signal terminals.

4. The grounding structure of the electrical connector as described in claim 1, wherein the insulating body is further provided with downwardly protruding positioning terminals corresponding to the two ends of the terminal group, the two positioning terminals engaging with the fitting portion inside the insulating body and the pull-out hole located below, and the fitting portion on both sides of the positioning terminals having an outwardly formed barbed structure.

5. The grounding structure of the electrical connector as described in claim 1, wherein the insulating body is provided with a plurality of fixing slots on the inner side of the terminal slots, and the positioning shoulders protruding on the inner side of the fixing slots are for fastening and fixing with a plurality of latches at the center of a fixing seat. On both sides of the latches are a plurality of first abutments of longer length and a plurality of second abutments of shorter length arranged in an alternating pattern. The first abutments abut against the inner side of the signal terminals and the second abutments abut against the inner side of the grounding terminals, and the first abutments can block electromagnetic waves generated around the signal terminals.

6. The grounding structure of the electrical connector as described in claim 5, wherein the insulating body has guide rails protruding at both ends of the bottom of the first mating space, and the two ends of the fixing seat are recessed at the locations corresponding to the two guide rails to form grooves for accommodating them.

7. The grounding structure of the electrical connector as claimed in claim 1, wherein one end of the signal terminals and the grounding terminals of the terminal group has a mating portion bent toward the first mating space, and a supporting portion abutting against the inner wall of the terminal slot is formed at the suspended end of the mating portion, and the other end of the signal terminals and the grounding terminals has an outwardly bent soldering portion.

8. The grounding structure of the electrical connector as claimed in claim 1, wherein the signal terminals and the grounding terminals of the terminal group are formed inside the insulating body by in-mold injection molding.

9. The grounding structure of the electrical connector as described in claim 1, wherein the grounding plate includes a long strip-shaped main body, with inwardly bent abutment arms extending from both the upper and lower sides of the main body, and both ends of the grounding plate are provided with a latching portion that protrudes outward and is embedded inside the insulating body.
